In-situ manufacturing of ODS FeCrAlY alloy via laser powder bed fusion

Creator:: Mirzababaei, Saereh, Ghayoor, Milad, Doyle, Ryan P., and Pasebani, Somayeh
Abstract:: Gas-atomized Fe–24Cr–8Al–0.5Y (wt.%) powder was used as a feedstock in a laser powder bed fusion process with nitrogen atmosphere. Formation of Al–Y–O-enriched nanoparticles with diameters of 10–100 nm implied in-situ precipitation of Al–Y–O-enriched nanoparticles within the ferritic matrix developing an oxide dispersion strengthened FeCrAl alloy without any mechanical alloying. Thermodynamics...

Simultaneous homogeneous and heterogeneous chemical reaction kinetics : thermal decomposition of nitrous oxide on a gold surface

Creator:: Halladay, Jeremy Brooke
Resource Type:: Dissertation

Transition Metal Oxides for Aqueous Electrochemical Energy Storage

Creator:: Jiang, Heng
Abstract:: In the 21st century, environmental deterioration is now an indisputable fact. Reliable and economically viable electricity systems based on renewable sources are urgently needed to replace the environmentally detrimental fossil fuels. The feasibility of incorporating renewable-but-intermittent solar and wind energy heavily depends on the development of cost-effective and safe technologies,...

Problems of Shape and Information in Multiscale Modeling of Transport Phenomena

Creator:: Ostvar, Sassan
Abstract:: This work is a compilation of problems that deal with multiscale analysis of transport phenomena in environmental systems. A common feature among the problems studied here is the presence of non-negligible microscale structure in various forms. Each problem is approached from the perspective that a macroscopic observable encodes aspects of...

Vacuum ultraviolet absorption studies of model sugar compounds

Creator:: Dickinson, Helen Rose
Abstract:: Vacuum ultraviolet absorption spectra of 13 model sugar compounds were measured in the energy range of 50 to 80 kK. The model sugars included three simple alcohols, four simple ethers, four cyclic alcohol-ether compounds, and two dioxanes. All spectra show transition bands in the energy region 50 to 65 kK....

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

Kinetic Prefactors of Reactions on Solid Surfaces

Creator:: Campbell, Charles T., Árnadóttir, Liney, and Sellers, Jason R. V.
Abstract:: Adsorbed molecules are involved in many reactions on solid surfaces that are of great technological importance. As such, there has been tremendous effort worldwide to learn how to theoretically predict rates for reactions involving adsorbed molecules. Theoretical calculations of rate constants require knowing both their activation energy and prefactor. Recent...

The development of the chlorinity-salinity concept in oceanography

Creator:: Wallace, William J.
Abstract:: This study traces the historical foundations of the concept of constant ionic proportionality and the equation (Salinity [S%₀] = 1.805 Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography since 1902 until 1969 and which is based upon this constancy, The notion that the constituents present in...

Fluorescence studies on the bases of the nucleic acids in solution at room temperature

Creator:: Hauswirth, William Walter
Abstract:: Fluorescence of adenine, guanine, thymine, cytosine, and uracil has been detected at room temperature in neutral aqueous solution using a digital signal accumulation technique and right angle fluorescence detection from solutions with absorbances between 0. 4 and 0. 7. The quantum yields are respectively 2.6 x 10⁻⁴, 3.0 x 10⁻⁴,...
